To test the communication link between the development and target computers, use these MATLAB® commands from the development computer
slrtpingtarget — The
performs a basic communication check between the development and target
computers. This command returns
Real-Time™ kernel is loaded and running and the development
and target computers are linked. Use this command for a quick check
of the communication between the development and target computers.
slrttest — The
performs a series of tests on your
Real-Time system. These tests
range from performing a basic link check to building and running real-time
applications. At the end of each test, the command returns an
failure message. If the test is inappropriate for your setup, the
command returns a
SKIPPED message. Use this command
for a thorough check of your
Link errors can also occur in the following instances:
The target computer is running an old Simulink Real-Time boot kernel that is not synchronized with the Simulink Real-Time release installed on the development computer. Recreate the target boot kernel for each new release.
If you have an active firewall in your system, you can experience communication errors. To work around this issue, add the MATLAB interface to the firewall exception list.
If multiple Ethernet cards or chips are installed in the target computer, see Timeout with Multiple Ethernet Cards.
